Abstract:
A method for manufacturing an impregnated segment includes forming a base tier by depositing one or more layers of molten metallic material. The base tier has a plurality of cavities. The method further includes inserting at least one superhard particle into each cavity and forming an additional tier on top of the base tier by depositing one or more layers of the molten metallic material. The additional tier has a plurality of cavities. The method further includes repeating the insertion of the superhard particles and the formation of additional tiers to form an impregnated cage.

Abstract:
A bi-metallic component including a first member of a first metal and a second member of a second metal different than the first metal. The first member includes at least one perforation. The second member is directly cast-in-place about a sheet-like portion of the first member and through the perforation to rigidly secure the first and second members. When used in an automotive vehicle, the second metal of the second member is preferably of aluminum and the first metal of the first member is preferably a high strength steel for spot welding to other steel structures.
Abstract:
A process of making a multilayer metallic casting includes steps of simultaneously forming a first layer of a first metallic material and a second layer of a second metallic material using a high speed continuous casting process, and continuously bonding the first and second layers to form a integrally cast multilayer metallic casting. The process may be performed using a twin-roll type continuous casting system having a continuous casting mold that includes a first mold compartment for receiving a molten first metallic material and a second mold compartment for receiving a molten second metallic. The molten first and second types of metallic material are quickly solidified into semi-solid shells and are pressed together by opposed casting rolls, creating a metallurgical bond between the first and second types of metallic material in order to form an integrally cast multilayer metallic casting. The process permits the high speed efficient manufacturing of near net shape multilayer metallic castings.
